Product catalog summary

General Specifications
The TTS144BVS-01 is a 1.44-inch TFT display module with a resolution of 128x128 pixels. It features an RGB stripe pixel arrangement and uses a TFT active matrix driver element. The active area measures 25.50mm by 26.50mm, and the module size is 29.0mm by 34.41mm by 2.20mm. The display is designed for a viewing direction of 6 o'clock and is controlled by the ST7735S IC. It includes a backlight with two white LEDs.

Interface
The module interface includes various pins for power supply, ground, data bus, and control functions such as chip selection, read/write enable, and reset. Notably, it features a tearing effect output pin for synchronizing the MCU to the frame rate.

Absolute Maximum Ratings
The supply voltage ranges from -0.3V to 4.6V, and the operating temperature is between -20°C and +70°C. The storage temperature ranges from -30°C to +80°C.

Electrical Characteristics
The typical supply voltage is 2.8V, with a maximum of 3.6V. The LED forward voltage ranges from 2.7V to 3.3V, and the input backlight current for one LED is 20mA.

Optical Characteristics
The display has a typical brightness of 200 Cd/m² and a contrast ratio of 600. The response time is between 25ms and 40ms. The viewing angles are 60 degrees horizontally and 70 degrees vertically.

Environmental / Reliability Tests
The module undergoes various tests, including high and low temperature operation and storage, thermal shock, electrostatic discharge, vibration, and shock tests, following IEC and GB standards.

Precautions for Use
Handling precautions include avoiding mechanical shock, preventing liquid crystal exposure, and careful handling of the polarizer. Storage should avoid direct sunlight and maintain recommended temperature and humidity conditions. During transportation, the modules should be protected from shock, pressure, and moisture.
